Patent CA-2244161-A1 (CA)
Inventor: BARDHAN BIBHUTI BHUSAN
IPC: G08G1/095
Filed: 1998-08-28
Abstract: At a multi-way intersection (that is, road junction), the vehicle that comes to a complete stop at the said intersection before any other vehicle or vehicles has the right of way (to cross the said intersection). However, there is an element of honest human error, or a possibility of other false judgment or inadvertent error or even of unscrupulous attempt to take advantage of any element of uncertainty, in deciding which vehicle does arrive or come to a complete stop before another at the intersection. This may cause anxiety in drivers and possible accidents. The present invention prevents or minimizes or eliminates such deleterious human factors by use of state-of the-art sensors, computer(s) and lights.

Title: Method & apparatus for electrically braking a motor
Inventor: SCHMIDT JOSEF
IPC: H02P3/12
Filed: 1998-09-24
Abstract: Converter-powered electric motors are often braked by electrical means. For this purpose the electronic converter that powers the motor is so controlled that the motor, when in generational operation, sends energy by way of the converter into an electrical braking resistor additionally connected to the converter, and this energy is there converted to heat. In order to avoid overloading the electrical braking resistor, an additional electronic or thermo-mechanical protective device is customarily provided. To simplify the arrangement, it is proposed in the present invention to provide as an electric braking resistor one made of a resistive material with a conductance that decreases progressively as the temperature rises through a certain range below the maximal acceptable operating temperature of the braking resistor. As a result, the power that can be accepted by the electrical braking resistor is made self-limiting, so that the braking resistor is protected against overheating.

Title: Apparatus for sputtering or arc evaporation
Inventor: WELTY RICHARD P
IPC: C23C14/34
Filed: 1998-11-25
Abstract: A linear magnetron cathode is disclosed which may be used as a vapor or plasma source for coating deposition or ion processing. The cathode has the shape of an elongated rectangular bar with vaporization of material  occurring  from an evaporable  surface wrapping around the periphery of the bar, along two opposite sides and around both ends.  A magnetic field is established over the entire evaporable surface which has a component parallel to the surface and perpendicular to the long direction of the cathode, forming a closed-loop magnetic tunnel around the periphery which directs an arc or sputtering plasma discharge.  The cathode may be configured for either sputtering or cathodic arc evaporation by choice of magnetic field strength and lateral confinement means. The invention provides uniform cathode erosion and a vaporized material  stream  in  two  directions  over  an  extended  length, permitting uniform deposition or implantation over large areas. Substrate mounting and movement geometries are disclosed which allow  efficient  use  of  the  bi-directional  vapor  emission distribution.
Patent CA-2258170-A1 (CA)
Title: Closure cap with temperature-dependent unscrewing protection
Inventor: REUTTER HEINRICH
IPC: B65D51/00
Filed: 1997-05-29
Abstract: The invention concerns a preferably screwable or attachable and twistable closure cap for attaching to a fixed spout, for example of a car radiator, a compensating reservoir in cooling or heating systems or the like, with a screw cap or an attachable and twisting cap and a twistable contact part within which preferably an excess/low-pressure combination valve is concentrically mounted on the cap. The valve has a sealing element which comes into tight contact with the fixed part when the closure cap is fastened. The closure cap, when screwed onto the fixed spout, is prevented from being removed or unscrewed or untwisted by means of a temperature-dependent control element in which the temperature-dependent control element (12) creates a coupling of the cap (2) and the contact part (4) when the temperature is normal and a decoupling when the temperature rises. In the area between the contact part (4) and the cap (2) on the top side of the contact part (4) there is a rocking coupling piece (50) which runs essentially in the radial direction of the contact part (4) which, on an axis (52) running parallel to the top side of the contact part (4), is firmly shape-mated with the contact part so that it has limited movement in a peripheral direction to the contact part and wherein the coupling piece (50) is pressed down by a spring element (62) in the direction of the top (58) of the contact part (4) when the temperature is normal. When the temperature rises the coupling piece (50) is pressed upwards against the spring element (62) using the temperature-dependent control element (34) and thus moved about its displaceable axis (52) so that its radial outer end becomes free and is no longer coupled with the cap (2).

Abstract: A method and an arrangement for controlling rock drilling on the basis of a pressure acting in a pressure conduit of a rotation motor of a drill rod. In the method, the pressure acting in the pressure fluid conduit of the rotation motor is measured during the rotation when the drill bit does not touch the rock to be drilled, and the control is carried out thereafter on the basis of the difference between the pressure value measured during the drilling and the idle pressure value. In the arrangement, the rock drilling machine comprises a control unit that measures the pressure acting in the pressure fluid conduit of the rotation motor when the drill rod is rotated so that it does not touch the rock to be drilled and stores it in the memory and controls the rock drilling machine during the drilling on the basis of the difference between the pressure value measured during the drilling and the idle pressure.
Patent CA-2259024-A1 (CA)
Inventor: DRAPER DARREN A
IPC: B60G11/18
Filed: 1999-01-12
Abstract: It is a swing-arm suspension system design to be used on but not limited to any type of trailer or boat. The swing-arm suspension system can be pined at different locations through a 75-degree arch to accommodate height settings for the application; the load resisting force is supplied by a torsion coil spring. The swing-arm suspension system design consists of the following pieces. A main shaft supported at both ends by bearings or bushings, housed in the intended application. A length of pipe, square tubing or solid stock is the swing-arm that is fixed by one end to the main shaft, at the opposite end it has a spindle/hub assembly fixed to it for wheel mounting. The torsion coil spring slides over the main shaft to encompass it. The swing-arm adjustment plate is then pushed on the main shaft along with wear washers. The torsion coil spring butts up to the swing arm at one end and held in place by retaining blocks, the opposite end of the torsion coil spring butts up to the swing-arm adjustment plate and attached to it by a spring retainer bracket. The swing-arm adjustment plate, which is free turning on the main shaft, rotates inside an adjustment plate locator bracket which has a hole drilled through it to correspond with holes drilled in the swing-arm adjustment plate. The adjustment plate locator bracket is fixed to the application that the suspension system is installed on. The holes in the swing-arm adjustment plate are at different locations along its 75 degrees of rotation. A pin is inserted through aligned holes in the swing-arm adjustment plate and the adjustment plate locator bracket to retain the suspension system at any given position for height adjustment of the application. When a load is applied to make the system work, the main shaft and swing-arm/hub assembly rotate in the bearings or bushings. The load is applied through the torsion coil spring to the pined swing-arm adjustment plate and adjustment plate locator bracket, keeping that end of the torsion coil spring from turning. The travel of the swing-arm is regulated by the amount of twist the torsion coil spring endures due to the load applied through it by the swing-arm/hub assembly at one end, and it's opposing end, which is held firmly by the pined swing-arm adjustment plate and adjustment plate locator bracket. The torsion coil spring twists, resisting the load, to a point where it can be twisted no farther and it stops.

Title: Distributed call system
Inventor: ARAVAMUDAN MURALI
IPC: H04L29/06
Filed: 1999-04-26
Abstract: Telephone service is supplied using a distributed architecture that employs a collection of resources each of which exposes a hierarchical namespace. The architecture includes two fundamental resource types, the device server and the call coordinator, which are interconnected by a network employing a common protocol, e.g., TCP/IP. The interaction between the various resources follows "client-server" principles to implement end-to-end communication. Device servers represent physical/logical telephone devices, which include a) end-point device servers and b) gateway device servers. End-point device servers 1) represent controls for communication, such as keypads, indicator lamps, and displays, and 2) perform media rendering, e.g., voice digitization, transport, and reconstruction. Gateway device servers have two "sides". One side is implemented to appear to a call coordinator as if it were a device server, and the other side has an interface adapted to interwork with a preexisting island of telephone service.  In the term "device server", "server" is used in the conventional manner of the "client-server" architecture, where the server serves request from the clients and does not take action unless it is in response to a client request. A call coordinator functions in the role of the "client". The device servers are unaware of communication state, which is maintained by the call coordinator and exposed as a hierarchical namespace. The call coordinator treats the processing of a call as a sequence of steps each of which can be implemented by a small piece of computer executable code called a "feature applet".
